Description
Technical Field
The invention relates to the field of film coating, in particular to a barrel film coating device and a barrel film coating method.
Background
Steel drums are one of the conventional containers in which they play an important role. Steel drums have evolved from the function of temporarily storing contents to today's industrial packaging, sales packaging, transportation packaging, etc.; from production to circulation and consumption, a consistently flowing container is formed, and a means for storing the articles in the container for a long time is formed, so that the steel drum can bring great change and progress to the work and life of human beings.
In the existing steel drum production process, the inner coating of the steel drum is generally made of epoxy resin, polyethylene resin, phenolic resin and other materials. During spraying and curing, there is a large amount of VOC (volatile organic compound) emissions. Also, a spray paint treatment is required on the outer layer of the steel drum, and VOC emissions are also present.
In order to reduce or avoid VOC emission, optimize the production flow simultaneously, raise the efficiency, reduce the manufacturing cost. The production process of the steel drum can be replaced by film-coated iron. Because the film-coated iron material can realize the preprinting of the pattern required by the steel drum and then coating, the common processing method is to use the film-coated iron with the printed pattern for processing to form the steel drum, thereby avoiding VOC emission.
However, when using coated iron for the ladle body, the ladle needs to be rolled and welded due to the large diameter of the ladle. This presents the following problems:
1) The circumference of the film-coated iron required by the steel drum body is longer (usually more than 3 meters), and the film-coated iron composite material with the full film cannot be subjected to welding operation after the drum is rolled, so that a certain welding area is required to be reserved on the steel drum when the film-coated iron raw material is produced, the film coating is not performed on the welding area so as to ensure that the welding of an interface can be performed, however, the difficulty of reserving the welding area is higher and the production cost is higher in the film-coated iron film coating process;
2) After the steel barrel body is welded, the welded area is metal and is not blocked by a plastic film, so that the area needs to be subjected to repair coating, and VOC (volatile organic compounds) emission is also generated;
3) The coated iron is also applied in early stage, is difficult to directly purchase in market, and needs to be produced by a targeted purchasing production line, and then is used for producing the steel drum, so that the production cost is high.

The first suction roller 12 sucks the outer film 14 unwound by the first unwinding mechanism 11, and attaches the outer film 14 to the outer wall of the cylinder 5 to be coated.
Specifically, in the embodiment shown in fig. 1, the first film coating assembly further includes a third suction roll 15 and a first cutter 16.

Meanwhile, in the production process, the cutting angle of the outer film 14 and the first adsorption roller 12 can be changed by adjusting the positions of the first steering roller 17 and the first guide roller 192 so as to adjust the flatness of the film surface of the outer film 14 before compounding and avoid the outer film 14 from wrinkling.
Similarly, the inner film 24 unwound by the second unwinding mechanism 21 is pulled to the second suction roller 22 by the second travelling robot 82, the inner film 24 is sucked by the second suction roller 22, then the second guide roller 292 in fig. 2 is moved in the direction of the second guide roller 291 (upward in fig. 2), the second guide rollers 292 and 291 are caused to sandwich the inner film 24 (i.e., the second guide roller 292 is moved to the position indicated by the broken line in fig. 2), and the second steering roller 27 is moved so that the second steering roller 27 contacts the inner film 24 (i.e., the second steering roller 27 is moved downward to the position indicated by the broken line in fig. 2), whereby the effect of guiding the conveying direction of the inner film 24 is achieved while the second steering roller 27 and the second guide rollers 291, 292 play a role of respectively securing the tension of the inner film 24. Meanwhile, in the production process, the cutting angle of the inner film 24 and the second adsorption roller 22 can be changed by adjusting the positions of the second steering roller 27 and the second guide roller 291 so as to adjust the flatness of the film surface of the inner film 24 before compounding and avoid the inner film 24 from generating wrinkles.
Further, when the film coating is completed, the first guide roller 192, the first steering roller 17, the second guide roller 292, and the second steering roller 27 are moved to the positions shown in fig. 2 in the directions indicated by arrows in fig. 2, and the outer film 14 and the inner film 24 are cut by the first cutter 16 and the second cutter 26, respectively.
This embodiment may also be implemented, and will not be described here again.
Further, the invention also provides a method for coating the cylinder by using the cylinder coating device shown in fig. 1 or 2.

Step S300: the first adsorption roller 12 of the first film-coating assembly adsorbs the outer film 14 unreeled by the first unreeling mechanism 11 to the outer wall of the heated cylinder 5. The second adsorption roller 22 of the second film-coating assembly adsorbs the inner film 24 unreeled by the second unreeling mechanism 21 to the inner wall of the heated cylinder 5. Specifically, the step of adsorbing the outer film to the outer wall of the cylinder by the first adsorption roller further includes the following sub-steps: the outer film 14 unwound by the first unwinding mechanism 11 is drawn to the first suction roll 12 by the first traveling robot 81 of the first film coating assembly. Similarly, the step of adsorbing the inner film to the inner wall of the cylinder by the second adsorption roller further includes the sub-steps of: the inner film 24 unwound by the second unwinding mechanism 21 is pulled to the second suction roller 22 by the second traveling robot 82 of the second film coating assembly.
